There are many kinds of sewage treatment plants which vary in the process by which they treat wastewater. We specialize in all sorts of wastewater treatment, and can design, build, and maintain a plant for you, customized to your requirements.

Some of the treatment plans we offer are the following:

Activated Sludge Plant (ASP)

Activated Sludge Plants are a common method of treating sewage water that use aeration, and organisms like certain bacteria and protozoa. It consists of 3 parts – an aeration tank, which serves as a bioreactor; a settling tank (final clarifier) to separate the solids from treated wastewater; and a return activated sludge equipment to transfer settled sludge from the clarifier to aeration tank. Activated Sludge Plants usually need to be serviced twice a year.

Rotating Disc System (RBC)

Rotating Disc Systems are also known as Rotating Biological Contactors (RBCs).They were introduced in the 1970s, and revolutionized the treatment of sewage water. RBCs are made up of 3 parts – the disc itself, the Primary Settlement Tank, and a bio-disc rotator. The effluents settle at the bottom of the tank, after which the rotating discs treat it before discharge into a stream, or other water body. This happens due to the growth of microorganisms on the disc that digest the unclean effluents. After this, there is an aeration process for dead bacteria and effluents to settle, and the cleaned effluent is discharged. RBCs require servicing either annually, bi-annually, or quarterly, depending on their use and making.

Membrane BioReactor (MBR)

A Membrane Bioreactor consists of a system containinga membrane, like microfiltration or ultrafiltration, being combined with a method involving biological processes to treat wastewater. These membranes are used to separate solid particles from the sewage or wastewater, so that organisms like bacteria can further treat the effluents an MBR is a version of the Activated Sludge Process, and recovers regular weekly maintenance. It requires servicing approximately once in six months.

Moving Bed BioFilm Reactor (MBBR)

MBBR uses the Activated Sludge Process, combined with biofilm media to effectively clean wastewater. MBBR systems can treat large amounts of wastewater thoroughly, while taking up little space. They use floating plastic carriers (media) within the aeration tank to increase the amount of microorganisms available to treat the wastewater.

Submerged Aerated Filter (SAF)

Submerged Aerated Filters are an ideal sludge dewatering mechanism to reduce organic matter from wastewater. The SAF process is based on individual cells arranged in a series through which the wastewater flows. Each cell contains a rigid block media on which biomass is formed, and a fine bubble diffuser system feeds oxygen from blowers in the control kiosk to promote its growth. Wastewater passes through the biomass which feeds on the Biological Oxygen Demand. After this, the clean effluent exits at the surface of the final cell. SAF systems require maintenance and service annually, six-monthly, or quarterly, depending on their usage.

Suspended Media Filters (SMF)

Suspended Media Filters use a filtration process, usually through a membrane, to remove suspended, insoluble impurities in water during pretreatment. Media Filters used in water & Wastewater treatment are either based on gravity or pressure, depending upon the flow of water. Water is pumped through a pressure filter, while it flows naturally due to gravity in a gravity filter.These filters employ granular media like sand, anthracite or activated carbon, either alone or in combination, as the filter media.

Sequencing Batch Reactor (SBR)

Sequencing Batch Reactors are industrial tanks used for wastewater treatment. They clean effluents from municipal and industrial machinery in batches.Oxygen is bubbled through the waste water to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to make itsuitable for discharge into sewers or for use on land. It consists of two tanks through which the wastewater flows. While one tank is in settle/decant mode, the other is aerating and filling.

Dissolved Air Flotation System (DAF)

Dissolved Air Flotation Systems (DAF) are an effective method of sludge treatment, and remove oil and grease from the wastewater to make it suitable for reuse. It is a clarification process that uses micro bubbles to attach and float flocculated particles and suspended solids to the water surface for removal. These floated sludge particles are then removed periodically in a desludging trough, and the clarified water flows to the bottom of the clarifying chamber, after which it is collected and released.

Trickling Filter

A Trickling Filter is a wastewater treatment system that uses the method of filtration to remove impurities. It is a fixed-bed system that uses aerobic processes, and the settled water is continuously trickled over the filter, causing a layer of biofilm to form. Aerobic conditions are maintained.
