Steel & Stainless Steel Fabrication

Water and Wastewater
Treatment Plant Equipment

3A Makina is a reliable fabrication partner to a wide variety of commercial, municipal, industrial organizations in the water and wastewater treatment industry, We are serving global industry leaders since 1985. We use our experience, expertise and flexibility to adapt different projects to deliver high quality, in-house built equipment. 

We understand the challenges of water and wastewater treatment applications, especially the requirement for high quality, custom fabricated equipment that can outlast the highly corrosive substances used for water treatment facilities.

Our fabrication facilities have been divided into two separate sections to prevent contamination of steel and stainless steel. We specialize in the custom design fabrication of a wide range of equipment using specialty steels including exotic steel and stainless steel grades.

Our services are not limited to fabrication, only. We offer testing, installation, logistics and startup services to minimize the costs of our partners.

3A Makina is ready to serve companies of all sizes to increase their competitiveness by providing high competitive prices without giving up on quality and without increasing the workload of the clients by handling all the documentation in a proper way.

Conventional Clarifiers

Sedimentation tanks or conventional gravity clarifiers are used in water and wastewater treatment as a physical unit operation through gravity for solid-liquid separation of readily settleable solids. The functions can be further enhanced using a solid contact clarifier which combines mixing, flocculation, and clarification in a single tank.

Dissolved Air Flotation (DAF)
Clarifiers and Thickeners

DAF systems are designed to remove total suspended solids (TSS), biochemical oxygen demand (BOD), and oils and greases (O&G) from a wastewater stream. Contaminants are removed using a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.

Filtration Modules

Ultrafiltration (UF), Microfiltration (MF), Reverse Osmosis (RO) are the water treatment processes of separating low molecular weight particles such as colloids and macromolecules from water with the help of a membrane filter by creating pressure.

Flocculating Clarifiers

Flocculation clarifiers are particularly effective for flocculation and clarification of municipal and industrial water supplies, screened primary sewage, wastes with high grit content, and industrial wastewater containing heavy settleable solids.

Gravity Thickeners

Gravity thickening increases the solids concentration by allowing the particles to settle to the base of a vessel, producing a concentrated (thickened) solids stream at the vessel base and a supernatant (diluted) stream at the surface.

High-Rate Thickener Clarifiers

High-Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to drop the solids, making High-Rate Thickeners environmentally friendly.

Package Treatment Plants

Package plants for biological wastewater treatment with activated sludge are a great way to achieve advanced wastewater treatment results in an economical manner.

Paste Thickeners

Paste Thickeners are used by mineral and aggregate producers, as well as environmental contractors, where the benefits of high-density underflow translate into savings in downstream processing costs, such as tailings storage facility costs, or lower volumes in leaching operations.

Pressure Filters

Pressure filters are similar in bed construction to rapid gravity filters, except that they are contained in a steel pressure vessel. Perforated pipes or a steel plate with nozzles are used for collecting the filtered water and for distribution of the wash water and air scour. The steel pressure vessel is cylindrical, arranged horizontally or vertically.

Rotary Vacuum Drum Filter

Rotary Vacuum Drum Filters process slurry and discharge cake in a continuous process. They can be used in wastewater treatment, sludge dewatering, chemical manufacturing, the pharmaceutical industry, cosmetics, mineral mining and refining, and the food processing industry. RVDFs are ideal for a slurry with variable cake thickness, moisture content, and stickiness.


Water screening is a critical feature of all municipal and industrial wastewater treatment plants because it retains particles contained in the wastewater. These solids must be removed at the start of the water treatment process because they can make the entire system less efficient, damage expensive and necessary water treatment equipment, or taint water, creating minor to big scale natural disturbances for a region’s entire ecosystem.

Screw Conveyors

Screw conveyors are the mechanisms that use a rotating helical screw blade to move bulk materials, both liquid and solid. In the modern industry, they are typically used at a horizontal angle or a slight incline to move semi-solid materials.

Sedimentation Tanks

Sedimentation tanks or settling tanks are the components of a modern system of water supply or wastewater treatment. A sedimentation tank allows suspended particles to settle out of water or wastewater as it flows slowly through the tank, thereby providing some degree of purification.

Sludge Removal Systems

Sludge Removal System collects sludge in surface water applications and effectively removes light sludges such as alum or ferric hydroxide or light iron and manganese precipitates in potable water supplies.

Solids Contact Clarifiers

Solids Contact Clarifiers combine the functions of chemical treatment, mixing, flocculation, and sedimentation. They have been used for the applications such as lime softening, colorant removal, removal of magnesium and iron, and more.
