Waste Water and Water Recovery

Ink Waste / Nuclear Waste / Chemical Waste / Prints and Dyes

With tougher regulations and industrial impact on our environments, our clients and governments are growing more conscious about their contribution to environmental sustainability and protection.

Impact on high waste COD waste water, ground water contamination and toxic polluting has put a strain on the valuable resources.

As a water hub nation for South East Asia, we tap on the expertise of water management, wether is it RO DI modules for ultra pure or portable water to nuclear waste regeneration for toxic water recycling , we develop complex solutions and provide suitable equipment for communities to industrial resolutions on water treatment.

The technology is based on boiling the waste water ; this water, once distilled, is replaced in the production line whereas the contaminant, now very concentrated, can be disposed off at relatively low cost.

The product to be distilled is sucked into the evaporator exploiting the depression inside the boiler, generated by the vacuum circuit. The cooling cycle, equipped with a heating pump, is able both to get heat the liquid in treatment and to cool the vapours produced in the boiling phase. Distilled liquid and the processed residue are unloaded at the end of the distillation process.

Strong point of this technology is the low running cost of its application. The vacuum distillation, combined with the heat pump technology, allows us to separate the water from the polluted products at a low energy consumption.

The range of FORMECO units equipped with heat pump includes models which can treat from 240 up to 3.500 litres per day. Personalised units, which exploit other sources of energy (steam, hot water or diathermic fluids), can be designed for higher capacities.

FORMECO evaporators are self-governing and they can work for 24 hours a day without any human intervention. They are manufactured from different materials and equipped to satisfy any specific request.

FORMECO units can be utilised in different fields : purification and concentration of waste water, recovery of food additives from different industrial process liquids, recovery of metals from washing processes, concentration of must, treatment of percolation water, etc.

The range of standard evaporators, equipped with heating pump, includes 4 different series :

– units equipped with immersed serpentine
– units equipped with heated surface and inner scraper for strong concentrations
– for corrosive liquids
– units with forced circulation for big production quantities

FORMECO evaporators allow :
– the separation between water and polluted products
– its immediate re-utilisation in the production line
– drastic reduction of waste water to dispose
– recovery of any raw materials contained
– design of waste minimisation plant

Treatment plant operation personnel typically do not consider a granular media filter as a piece of equipment. Filtration is viewed as a distinct unit process and filtration is accomplished with a filter but somehow the connection that a filter is actually a piece of equipment never occurs to many operators or managers. In reality the granular media filter is easily the most costly and most complex piece of equipment in a water filter plant.

We provide a good range of filters from mix media to sand, with careful consideration on the clients cost of operations and also operation replacements.

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device

We provide modular units for up to 300m3/hr.

Foam is composed of dissolved organic compounds (DOC) which bind together on the outside of an air bubble. These DOC’s have a sticky surface which will attract minute detritus. DOC’s exist in our ponds primarily because of fish waste, uneaten fish food, decaying plant material and organic soils. If you have had a fish spawn, you will have an overload of DOC’s! DOC’s are difficult to eliminate through mechanical filtration. There is some elimination through biological means either by plants in your pond, including algae, or your biological filters. One way to substantially reduce DOC’s is by water changes, preferably having a surface skimmer draining to waste, but your water bill may go up substantially. One of the most effective ways to substantially reduce DOC’s is with a foam fractionator.

A lamella clarifier or inclined plate settler (IPS) is a type of settler designed to remove particulates from liquids.

They are often employed in primary water treatment in place of conventional settling tanks.

They are used in industrial water treatment. Unlike conventional Clarifiers they use a series of inclined plates. These inclined plates provide a large effective settling area for a small footprint. The inlet stream is stilled upon entry into the clarifier. Solid particles begin to settle on the plates and begin to accumulate in collection hoppers at the bottom of the clarifier unit. The sludge is drawn off at the bottom of the hoppers and the clarified liquid exits the unit at the top over a weir.

Lamella clarifiers can be used in a range of industries including mining and metal finishing, as well as used to treat groundwater, industrial process water and backwash from sand filters.

Lamella clarifiers are ideal for applications where the solids loading is variable and solids sizing is fine and are more common than conventional clarifiers at many industrial sites due to their smaller footprint.

One specific application is as pre-treatment stage for effluent entering membrane filters. Lamella clarifiers are considered to be one of the best options for pre-treatment ahead of membrane filters.

Further lamella clarifiers are able to maintain the required water quality to the membrane without the use of chemicals. This is a cost saving measure both in purchasing chemicals and limiting damage to the membrane, as membranes do not work well with the large particles contained in flocculants and coagulants.

Lamella clarifiers are also used in the municipal waste water treatment processes. The most common wastewater application for lamella clarifiers is as part of the tertiary treatment stage. Lamella clarifiers can be integrated into the treatment process or stand-alone units can be used to increase the flow through existing water treatment plants.

One option for integrating lamella clarifiers into existing plants is for conventional or sludge blanket clarifiers to be upgraded by attaching a bundle of inclined plates or tubes before the overflow in the so-called “clear water zone”. This can increase the settling area by two-fold resulting in a decrease in the solids loading in the overflow.
