Lamella Clarifier High Flow Capacity Sedimentation Systems

Water Lanka is engineered for high flow rate sedimentation and settling of flocculated wastewater streams. These units are pre engineered, pre assembled, and factory tested ensuring reliable operation and minimizing site installation and start up time. High flow rate sedimentation and settling in a Lamella Clarifier works by having a flocculated liquid and solid stream cleanly separated. These units are meticulously designed to ensure reliable operation and reduce site installation times.

Dissolved Air Flotation (DAF) Clarifier Advanced TSS and FOG Removal Technology

DAF machines are designed to remove total suspended solids (TSS), biological oxygen demand (BOD), and fat, oils, and greases (FOG) from a wastewater stream. Contaminants in wastewater streams are removed by introducing dissolved air into a water solution, artificially injecting air under pressure into a recycle water stream of clarified effluent. This recycle stream is then combined and mixed with influent wastewater in a DAF contact chamber. The solution forms micro bubbles that attach to the contaminants. The contaminants rise to the water surface and are removed by a surface scraper mechanism into a sludge hopper for further dewatering.

Sequencing Batch Reactors (SBR) Activated Sludge Wastewater Treatment Systems

Sequencing batch reactors (SBR), also known as sequential batch reactors, are activated sludge systems applied in wastewater treatment. SBR systems are upgrades of conventional activated sludge systems that minimize footprint by integrating separate functions in a single treatment system. Standard SBR setups usually include the reactor basin, water sludge draw off mechanism, effluent decanter, and process control system.

Water Demineralization Plant (DM Plant) Commercial Deionized Water and Ion Exchange Systems

Water that has mineral ions removed is called demineralized water, usually referred to as deionized water. Mineral ions like sodium, calcium, iron, and copper cations as well as anions like chloride, sulfate, and nitrate can be detected in water. Deionization is a physical procedure that creates H+ and OH ions by replacing the mineral salts in water through the use of specially designed ion exchange resins. Deionization creates high quality water that is normally comparable to distilled water. It is rapid and scale free because the bulk of water contaminants are dissolved salts. A DM water system works on ion exchange, degasification, and polishing tenets to provide water that is mineral free. Demineralized water systems are extensively used in the fields of cooling, power processing, and steam.

Water Softening Plant Hardness Reduction for Manufacturing & Boiler Feeds

The water softening plants are designed to produce soft water to suit various industries. Soft water provides consistent quality with low residual hardness throughout the service cycle. High quality synthetic acid cation resin is used to exchange sodium ions with calcium and magnesium ions which form water hardness. After reaching the desired output of soft water, the resin is regenerated with a sodium chloride solution. These units are easy to operate. These models are available to produce various capacities of soft water required.

RO Plant Sri Lanka & Reverse Osmosis Treatment High Pressure Desalination & Purification Systems

If you are looking for a reliable RO Plant in Sri Lanka, Water Lanka engineers industry leading solutions. The reverse osmosis process works by utilizing high pressure pumps to elevate osmotic pressure on the concentrated side of the RO unit and push pure water through the membranes. RO is a highly effective water treatment method that needs a higher degree of pressure depending on the total amount of dissolved solids contaminants existing in the raw water. The treated water that has been removed of its dissolved solids is now referred to as permeate or product water. The concentrated flow of contaminants left behind in the brine is referred to as reject flow and will be discharged.
