Based on required water quality and your specific project needs, we can customize and design conform your requirements, using cost effective technologies, which can be simple or state-of-the-art.
Depletion of water resources in urbanized area that associated with population growth, business activities expansion and the impact of climate change has been an issue in the last 2 decades. Only around 1.2% of all freshwater is surface water, which serves most of life’s needs, while the big apart of water resource on earth is saline water in the ocean, counts about 97%. Hence, finding for affordable, acceptable and reliable solutions to supply fresh water with appropriate quality has become a challenge for water suppliers.
Dissolved Air Flotation (DAF) system is a very effective clarifier system where solid or liquid particles are separated from a liquid phase. Separation is brought by introducing fine bubbles into the liquid phase. The bubbles attached to particulate matter, and the buoyant force of combined particle and gas bubbles is great enough to cause the particle to rise to the surface. Particles that have higher density liquid can thus be made to rise. The rising of particles with lower density than the liquid can also be facilitated i.e. oil suspension in water. Once particles have been floated to the surface, they can be collected by skimming operation.
Lamella clarifier is used to remove particulates i.e. sludge, sand and silts in surface water, chemical precipitation and flocculation form solids from liquids. The most economic process to remove this pollution by using inclined plate sedimentation. This plates provide a large effective settling area for a small footprint.
Multi-media filter is used in water treatment plant to remove suspended solids like silt, clay, organic matter, algae and microorganisms from the process water. The suspended solids particles that can be removed is as low as 10-40 microns. When coagulant is used to the feed, it can reduce until 5-10 microns. As a result, the turbidity level in the treated water can be reduced.
A typical multi-media filter setup contains three layers of filling; anthracite, quartz sand and garnet/gravel. These materials are graded according to its specific density within a pressurized vessel. Depending on the type of water to be treated, the velocity applied usually in the range of 6-15 m3/h.m2.
Over the time as the turbidity removed from the feed water, the filter will experience high pressure drop. At this point, the backwashing through the media filter should be performed.

Ion exchange (IX) resins are polymers matrix on which the functional group are attached. The functional group are capable of exchanging their ions within the polymer (either positively or negatively charge), with ions of different species in solution. These resins are usually designed as granules, beads, or sheets. They appear solid, even under the microscope, but on a molecular scale the structure is quite open. The beads are typically porous, providing a large surface area on and inside them. ‘Catching’ ions occurs along with the accompanying release of other ions: this is the reason why the process is called ion exchange.
Membrane bioreactor (MBR) is defined as a combination of a biological process like activated sludge process with membrane separation using micro/ultrafiltration. It is broadly used for treating municipal and industrial wastewaters. Compared to conventional biological treatment system, it has several advantages, among others high effluent quality, limited space requirements, no secondary clarifier needed, possibilities for phased extension of the treatment plant.
Sequencing Batch Reactor (SBR) system is a variation of the activated-sludge process for treatment of waste water. SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter (measured as biochemical oxygen demand (BOD) and chemical oxygen demand (COD). The treated effluent may be suitable for discharge to surface waters or possibly for use on land.
Wastewater Evaporation technologies have been widely used in wastewater treatment application due to its effectiveness in removing salts, heavy metals and any other hazardous materials from solution. In certain applications, it is used for recovering useful by-products from a solution, or to concentrate liquid waste in order to reduce the cost of final disposal. Evaporators also can turn the wastewater into clean water for the pupose of reuse (i.e. zero liquid discharge), hence eliminates make-up water requirement.
