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
minimising site installation and start-up time.
High flow rate sedimentation and settling in a Lamella Clarifier works by having a flocculated liquid/solid stream
Dissolved Air Flotation (DAF) Clarifier
Flotation is a general method used in water treatment to liquid solid separation. The general process involves the flotation of particles to the surface of the liquid where they are concentrated and removed by physical means. Dissolved Air Flotation (DAF) is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated
Sequencing Batch Reactors (SBR)
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)
Demineralization is a type of water purification. demineralization refers to the removal of dissolved solids from feed water and process streams. If you’re investigating options for water treatment and purification While it can refer to any treatment process that removes minerals from water, the term demineralization is typically reserved specifically for ion exchange processes used for near-total removal of ionic mineral contaminants. Often, the terms demineralization and deionization are used interchangeably...
Water Softening Plant
A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water.
These “hardness ions” cause three major kinds of undesired effects. Most visibly, metal ions react with soaps and calcium-sensitive detergents, hindering their ability to lather and forming a precipitate - the familiar “bathtub ring”. The presence of “hardness ions” also inhibits the cleaning effect of detergent formulations.
Reverse Osmosis (RO) Water Treatment
Reverse osmosis is a method used to separate a high percentage of pollutants from water by forcing it through a semi-permeable membrane. Reverse osmosis operates by utilizing advanced filtration technology which removes dissolved ions from water. Osmosis is an elemental force that draws fresh water to water with higher salt content. This is a process by which dissolved ions are removed from the water. This elemental force can be surmounted by applied pressure with the usage of pumps and semi-permeable membranes, which forces water through the membrane and filter out dissolved salt from the water with the lowest energy requirements, some of the highest recovery rates, and one of the best rejection rates.
