Coagulants and flocculants are materials formulated to assist in
the solids or liquid separation of suspended particles in solution.
Such particles are characteristically very small and the
suspended stability of such particles (colloidal complex) is due to
both their small size and the electrical charge between particles.
Thus, conditioning a solution to promote the removal of
suspended particles requires chemical coagulation and/or
flocculation. A variety of flocculants and coagulants are available,
with different chemistries, molecular weights, charge ratios and
other attributes. It is critical that the appropriate flocculants and
/or coagulant be chosen to ensure cost-effective performance in
a solid/liquid separation process.
Experts said that the choice is dependent on process conditions,
including variables such as feed particle size, water chemistry,
system pH, per cent feed solids, etc. The new formulation
developed from waste material is an alternative to the readily
available flocculants/coagulants.
This technology was developed by employing used bleach earth
components as flocculants or coagulants for wastewater
treatment to remove impurities from water and down streaming
process of industrial fluids including algae. The technology works
by allowing the material to extract and utilise the metals or non-
metals from activated bleaching earth and waste-activated
bleaching earth by a chemical treatment process using acid or
alkali. The advantages of the technology are:
• This product can be safely used for biomass recovery
• It may lead to the concept of zero waste for the
treatment of industrial wastewater
• Ha multipurpose applications as it can be used for palm
oil Industry, paper mill industry and other industries to
treat their wastewater (multipurpose application)
• The final pH after flocculation/coagulation process is
about neutral as it is a neutralisation process
The invention has been protected via the lodgement of a Malaysian patent

The proposed business models are: (1) This product can be supplied straight to the end user; (2) It can also be licensed to an interested industrial partner that can manufacture and market it. The inventors would like to speak to companies interested in partnering.
According to BCC Research, the global market for specialty
chemicals for water treatment technology was worth USD 21.0
billion in 2008. This was expected increase to USD 27.9 billion in
2013, a compound annual growth rate (CAGR) of 5.8%. The
market is broken down by type of chemical and includes
corrosion inhibitors, coagulants and flocculants, biocides, scale
inhibitors, pH adjustors and softeners, fluorochemicals, activated
carbon, defoaming agents and others. Corrosion inhibitors have
the largest share of the market, worth an estimated USD 4.6
billion in 2008. This segment should reach USD 6.1 billion in
2013, for a CAGR of 5.8%. Coagulants and flocculants have the
second largest market share, generating an estimated USD 4.1
billion in 2008 and increasing to USD 5.4 billion in 2013, for a
CAGR of 5.7%. There are 3 major producers of inorganic
coagulants and flocculants in Malaysia. CCM Chemicals led the
market with 33% share. Malaya Acid Works and Malay Sino are
also firms that have strengths in inorganic type of commodity
coagulants and flocculants with 25% and 17% of the market in
Malaysia. Nalco and Ciba Specialty Chemicals shares about
7%, while Kurita held 6% of the market. Nalco and Ciba focused
more on organic chemicals.
