Wastewater Treatment

The amount of wastewater produced by humans, their manufacturing, and process industries is such that it cannot be sufficiently removed by the natural water purification process, which also affects aquatic life and animals. Wastewater is treated to get rid of pollutants and suspended solids. This clean, potable water can then be released back into the environment. Water Lanka design and manufacturing Process water treatment plants, Wastewater treatment plants, Sewage treatment plants for Sri Lanka industries for meet theair water treatment requirements.......

Sequencing Batch Reactor

For the treatment of wastewater, sequential batch reactors (SBR) or sequencing batch reactors are a kind of activated sludge technology. Batch treatments of wastewater from anaerobic digesters, mechanical biological treatment plants, or sewage are carried out in SBR reactors. With the goal to reduce the amount of organic matter (measured as biochemical oxygen demand (BOD) and chemical oxygen demand (COD)), oxygen is bubbled through the mixture of wastewater and activated sludge. The treated effluent can be suitable for land use or for disposal to surface waters......

Frequently Asked Questions: Water & Wastewater Treatment Sri Lanka

What is a Package Sewage Treatment Plant (STP) and why is it needed in Sri Lanka? +
A Package Sewage Treatment Plant is a compact, pre-engineered biological treatment plant that processes black and grey wastewater on-site. In Sri Lanka, commercial apartments, hotels, and schools require CEA Environmental Protection Licenses (EPL) to operate. Water Lanka package STPs eliminate toxic odors, occupy minimal ground space, and purify sewage so it can be reused for lawn irrigation or safely discharged into municipal drains.
Does Water Lanka supply both equipment and water treatment chemicals? +
Yes! Water Lanka Services (Pvt) Ltd is a complete single-source supplier. We manufacture and import the equipment (RO, DM, STPs, clarifiers, filter presses, pumps, blowers, filters) and also supply all treatment chemicals (PAC, Anionic/Cationic polymers, resins, activated carbon, and antiscalants) with continuous islandwide technical support.
How can I get an on-site inspection or formal project quotation? +
You can reach our engineering hotline directly at 076-459-1234 / 011-4758810, send a WhatsApp message to +94 76 459 1234, or email us at info@waterlanka.com. Our senior water engineer will schedule an on-site survey and provide a detailed BOQ and layout proposal within 24 to 48 hours.
