Chandwin Engineering Pte. Ltd. Singapore

Environmental engineering company providing advanced biological water treatment solutions for a wide range of industrial activities
We offer our customers comprehensive solutions for environmental projects, covering the following services: analysis, planning, design, construction, installation, maintenance and delivery of plants and capital equipment for natural water, municipal and industrial wastewater treatment.

Since our company was founded, we have promoted the best available technologies for industrial and domestic wastewater treatment and purification to provide our customers with the best solutions for their specific needs.
Industrial wastewater
Tertiary treatment of organic impurities, petroleum products and heavy metal ions to produce water of technical quality for use in agriculture, urban parks and other activities.
Municipal wastewater
Water purification to "conditionally clean" quality, neutral for the environment and containing no harmful micro-impurities (antibiotics, synthetic surfactants, etc.). Purification of water for human consumption. Maintenance of the water distribution and sewerage network.
Lakes and ponds
Purification of water to potable quality from surface fresh water sources. Purification of water from bio-ponds to produce deeply purified technical water of optimal quality for returning water to the environment.
Desalination
Removal of salts from water, preparing it for technological and domestic consumption. Demineralization of polluted and saline water (up to 3500 mg/l) at minimum cost up to 90% to make it suitable for irrigation or human consumption.
Water accumulation and storage
Water terminals designed for accumulation and storage of treated fresh water. Modular RFW water storages. Pure (treated) water storage in closed-type water storage terminals with permanent circulating treatment.
Operation and maintenance
We operate and maintain complex wastewater treatment plants in any climate zone. CHANDWIN ENGINEERING's operation and maintenance specialists ensure optimum treatment efficiency for both industrial and municipal customers.
Comprehensive wastewater treatment solutions
Our water treatment and wastewater treatment solutions range from plants for recycling and reusing wastewater from all origins for integrated water services to desalination and overall water management.

  • Low cost pure water*;
  • Scalable to any volume;
  • Guaranteed service life of 25 years;
  • No skilled personnel required in operation;
  • Treatment without harsh chemicals;
* Compared to traditional reagent and membrane treatment technologies.

Deep cleaning technologies

Global environmental awareness and attention to water conservation and pollution have led to stricter regulations on the use and discharge of industrial water.
Chandwin Engineering's zero discharge technology is ideally suited to enable many industries to clean and recycle their process water and recover valuable chemicals and compounds.
  • Chandwin Engineering's treatment systems are designed to remove dissolved solids from wastewater and return clean water back into the process.
  • Chandwin Engineering's zero-discharge technologies ensure that production processes comply with environmental regulations and are specifically designed to recover valuable salts from effluent streams prior to disposal, to generate additional revenue.
  • Chandwin Engineering can provide a complete portfolio of technologies to recover valuable by-products that can be commercialised.
