RemTech is a biopolymer for contaminated water treatment for metals and hydrocarbons
RemTech is a Seaweed-derived treatment reagent designed for water and wastewater treatment, capable of simultaneously treating hydrocarbons, oil and grease, and dissolved heavy metals in a single treatment step. Acting as an alkalizing and oxidizing agent, RemTech enables the selective removal of metals such as arsenic, manganese, and nickel while integrating with existing treatment systems.
In plain terms
RemTech is a Seaweed-derived water and effluent treatment reagent designed to act as an alkalizing and oxidizing agent in water and wastewater treatment applications. By increasing pH and promoting controlled oxidation, RemTech converts dissolved contaminants into insoluble forms, enabling the precipitation of heavy metals and the treatment of dissolved and emulsified hydrocarbons, including aromatic compounds, prior to conventional coagulation, flocculation, and solids separation processes.

What is RemTech?
RemTech is a liquid Seaweed-derived solution developed with alkalizing and oxidizing functions for water and wastewater treatment across municipal, industrial, mining, and environmental operations.
The solution supports the treatment of dissolved heavy metals, hydrocarbons, oils, and greases while promoting contaminant precipitation prior to conventional coagulation, flocculation, and solids separation processes. RemTech helps simplify treatment operations, reduce equipment wear, and lower the generation of residual sludge requiring downstream handling, with around 33% lower sludge generation depending on water chemistry and operating conditions.
What problems does RemTech solve?
Conventional water and wastewater treatment systems often require high dosages of alkalizing reagents such as lime, caustic soda, and soda ash, multiple preparation stages, and strict operational control to treat contaminants including dissolved heavy metals, hydrocarbons, oils, and greases. These processes may generate excessive sludge volumes, increase disposal requirements, raise logistics costs, and accelerate equipment wear caused by abrasive or highly reactive conventional reagents.
Many municipal, industrial, and mining water streams also contain multiple contaminants simultaneously, including difficult-to-remove metals such as arsenic (As), manganese (Mn), aluminium (Al), chromium (Cr), lead (Pb), iron (Fe), nickel (Ni), and aromatic hydrocarbons associated with BTEX compounds. In addition, powdered reagents often require dilution, slurry preparation, and dedicated dosing systems, increasing operational complexity and treatment time.
RemTech simplifies the treatment process through a fast-acting liquid Seaweed-derived formulation that can be dosed directly into existing treatment systems prior to coagulation and flocculation. The solution reacts quickly, requires lower dosage rates, and helps reduce sludge handling, transportation, and disposal costs depending on process conditions.
How does RemTech work?
RemTech acts as a fast-acting alkalizing and oxidizing reagent designed for water and wastewater treatment. By increasing pH and promoting controlled oxidation, the solution converts dissolved contaminants into precipitable forms, enabling the selective removal of heavy metals while supporting the treatment of hydrocarbons, oils, and greases prior to conventional coagulation, flocculation, and solids separation processes.
Its liquid Seaweed-derived formulation can be dosed directly into existing treatment systems, helping simplify operations, reduce reagent handling complexity, and support efficient contaminant removal across a wide range of water and effluent applications.

How to Apply RemTech
1. RemTech
RemTech is dosed directly into the treatment tank under continuous agitation during the pre-treatment stage. Acting as an alkalizing and oxidizing reagent, the biopolymer increases pH, promotes controlled oxidation, and converts dissolved contaminants into precipitable forms, supporting the removal of heavy metals, hydrocarbons, oils, and greases prior to solids separation.
2. Coagulant or Coagulant/Flocculant
Following RemTech application, coagulants or integrated coagulant/flocculant systems are applied according to water chemistry, contaminant profile, and treatment objectives. This stage promotes contaminant destabilization, particle agglomeration, clarification, and sludge separation.
3. Optional Complementary Oxidation
For water streams containing biological load, ammonia, nitrate, phosphate, or other nutrient-related contaminants, additional oxidizing reagents may be incorporated to support the overall physicochemical treatment process and optimize downstream contaminant removal.
4. Clarification and Solids Separation
Following chemical treatment, the precipitated and coagulated contaminants are removed through settling, flotation, filtration, or other solids separation processes according to plant design and treatment objectives.
Technical Notes
Depending on water chemistry and process design, some treatment systems may operate without a separate flocculant, as the selected coagulant may provide sufficient particle agglomeration and clarification performance.
When complementary oxidizing reagents are required, the dosing sequence may vary according to contaminant profile, reaction kinetics, oxidation demand, and process objectives. Oxidants may be applied before, together with, or after RemTech depending on the treatment strategy.
