WATER CLARIFICATION SYSTEMSThe clarification process is important in water or wastewater treatment, as it involves the removal of suspended solids, resulting in a clarified process stream. In water treatment, the process of clarification is often accelerated through the applications of coagulants and flocculants, in order to enhance gravity settling. READ MORE |
|
INTRODUCTION
The process of removing suspended solids, in order to produce a clarified process stream is important to ensure water treatment and wastewater discharge requirements are met. There are a variety of different clarification systems available in a range of different configurations and sizes that can be tailored to meet individual project needs.
Before raw water or wastewater enters a clarifier, coagulants and flocculants are usually applied, in order to instigate the finely suspended particles to clump together and form larger and denser particles, called flocs, that settle relatively quickly, compared to untreated feedwater. The upstream chemical pre-treatment process is desirable as it allows the separation of the solids in the clarifier to occur more efficiently. The clarifier works by permitting the heavier and larger particles to settle to the bottom of the clarifier. The particles then form a layer of sludge at the base of the clarifier requiring regular removal and disposal. The clarification process is commonly used at the early stages of water treatment as it reduces the solids loading and minimises downstream water treatment processes like filtration.
Tubes or Lamella plates are commonly used in rectangular clarifiers to increase the settling capacity by reducing the vertical distance a suspended particle must travel. High efficiency settlers use a stack of parallel tubes, rectangles or flat pieces separated by several centimetres and sloping upwards in the direction of flow.
These structures work providing a very large surface area onto which particles fall and become stabilized, aggregating very fine particles that can settle as the flow exits the plates. Structures inclined between 45° and 60° allow gravity drainage of accumulated solids. Tube settlers may allow the use of a smaller clarifier and may enable finer particles to be separated with residence times of usually less than 10 minutes. OUR OFFERING

MEDIA FILTRATION SYSTEMSFiltration is a key processing step in the treatment of water and wastewater, usually consisting of a physical and sometimes a chemical separation process. Multimedia filtration, a more complex form of media filtration, involves the physical removal of coarse components and more refined removal of colour, odour and chemicals. READ MORE |
|
INTRODUCTION
Due to its simplicity, media filtration is one of the most widely used forms of water treatment. The media filtration process involves sequential treatment, by passing a feedstock through a series of media types, in order to achieve the desired levels of impurity removal. In the process of removing physical components such as suspended solids, the gradual accumulation of entrapped solids within the granular media occurs, which requires the intermittent removal by means of a standard backwash cycle. Following physical filtration, the filtrate is often treated with granular activated carbon (GAC) for the removal of organics, colour, odour and chemicals including chlorine, which can be damaging for membrane-based filtration processes, including reverse osmosis.

MEMBRANE FILTRATION SYSTEMSThe presence of physical contaminants in raw water or process water streams can present challenges to the use or subsequent treatment of the process stream. An effective membrane filtration system is able to reduce the presence of physical contaminants, including suspended solids, resulting in a cleaner supply of water. READ MORE |

GROUP STRUCTURE
In order to satisfy the increasing water quality requirements for potable water, industrial and other specialist water requirements, the removal of suspended solids represents an important requirement. In recent years, a range of membrane filtration processes have been adopted, in order to address these requirements. Membrane filtration is commonly utilised as part of an efficient solids removal system, in application where solid material is entrained in a process fluid, including raw water. In some instances, the membrane filtration system removes the requirement for more conventional pre-treatment processes, ensuring cost effective filtration as well as water treatment plants with a reduced footprint.
Given membrane filtration is a physical separation process, the selection of an appropriate membrane pore size can be selected to remove specific impurities, down to virus sized particles.
Typical Membrane Filtration Scale
During the filtration process, the solid particles that cannot pass through the filter membrane are described as oversize and the fluid that passes through the membrane is called the filtrate. Oversize particles may form a solid layer on the filter membrane and may also block the filter pores, preventing the fluid phase from crossing the filter membrane – this process is referred to as blinding. The size of the largest particles that can successfully pass through a membrane filter is called the effective pore size of that filter. The filtration process results in a gradual accumulation of entrapped solids on the membrane surface, which require intermittent removal by means of a filter wash cycle and occasionally a more intensive membrane cleaning process. Expertise in the design and operation of an appropriate membrane filtration system will ensure efficient solid-liquid separation, high performance and long life of the membrane filtration system.

REVERSE OSMOSIS & UPW SYSTEMSIn order to meet high quality water requirements, reverse osmosis (RO) and ultrapure water (UPW) systems are designed to produce water with very high purity. The specific water requirements for a given application, determine the appropriate water treatment options necessary to achieve the requisite quality of water. READ MORE |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||
GROUP STRUCTURE
Reverse osmosis (RO) is a process where a fluid, typically water, containing dissolved minerals is deionised by pressurising and pushing the fluid through a semi-permeable membrane. By applying pressure during the RO treatment process, the membranes typically retain 95–99% of the dissolved solids (mostly salts) from the raw feed stream into a concentrate. At the same time, the resulting permeate stream is mostly depleted of the dissolved minerals and is suitable for a range of applications. RO technology is utilised in desalination plants, utilising both brackish as well as seawater as feedwater, BWRO and SWRO, respectively. In addition to the utilisation of RO treatment for drinking water production through desalination, RO systems are also utilised in water softening systems in the hospitality and health sectors, as well as industrial applications including boiler make up water systems in power generation. Other industrial applications include the adoption of RO systems for dewatering of process and waste streams, in order to reduce overall volumes product or waste volumes.
Similar to RO systems, ultrapure water (UPW) systems produce high purity water through the removal of contaminants. In order to produce ultrapure water, most UPW systems utilise multistage purification steps including reverse osmosis, ion exchange and ultraviolet disinfection for contaminant destruction.
Small-scale packaged UPW systems are commonly used in laboratory settings, particularly medical and analytical laboratories, where it is important to ensure that treated water is not a source of contamination. In larger scale industrial settings such as the semiconductor industry, where bulk volumes of ultrapure water are required, specific process steps are adopted to remove particular contaminants from a given feedwater.
Ultrapure Water Guidelines The ASTM (American Society for Testing and Materials) defines 4 different standard grades for pure water used in laboratories.

DISINFECTION SYSTEMSMost common types of water contain a spectrum of biological organisms from algae through to bacteria and viruses, many of which can be highly pathogenic, that is responsible for causing disease. An effective disinfection system, is able to reduce or eradicate water borne organisms, resulting in a safer supply of water or wastewater. READ MORE |
|
INTRODUCTION
In order to satisfy the increasing water quality requirements for potable water, industrial and other specialist water requirements, the removal of biological organisms represents an important requirement. In recent years, a range of disinfection processes, most commonly, chemical dosing and UV disinfection processes have been adopted, in order to address these requirements. Traditionally, chlorination, or the process of adding chlorine to water, most commonly achieved through the addition of sodium hypochlorite, or less commonly through the injection of chlorine gas, has been utilised in order to destroy common pathogens. More recently, ultraviolet (UV) based disinfection systems are increasingly being used to reduce or eradicate water borne organisms including algae, bacteria, fungi, viruses, including common pathogens such as E.coli, fecal coliform, enterococci, fusarium, kerboard-bacter, ralstonia pythium and phytobacteria, giardia, legionella and salmonella. The convenience of UV based disinfection systems is considered by many water treatment operators as a safer alternative to chemical-based dosing systems, however, the most optimal disinfection solutions will depend on the quality of the feed, process or wastewater being treated, and the specific objectives/requirements for the disinfection process.
