Completed Projects


Sewage Treatment plants in Bangladesh are growing businesses due to environmental aspects. Nowadays Sewage Treatment Plant is mandatory to all ships because the sewage generated on the ship cannot be stored on the ship for a very long time and for this reason it has to be discharged into the sea. Though sewage can be discharged into the sea, we cannot discharge it directly overboard as there are some regulations regarding discharging of sewage that needs to be followed.

Our group has taken this opportunity for installing STP  (Sewage Treatment Plant) for 150 persons of Naval Ship Ali Haider under the Bangladesh Navy. The STP was demanded by the UN from an environmental point of view. Ali Haider is the largest and well equipped frigate which is deployed for UN missions in Lebanon. By which Bangladesh Navy is earning a handsome amount of foreign currency indeed. It should be mentioned that this is the first STEP in a Bangladeshi Frigate so far. Our plant is constructed and tested under very strict standards ensuring trouble-free operation in any environment.



A Mobile Water Treatment Plant is an equipment, by which one can ensure safe and WHO standard  drinking water from any kind of source water in any time any place. Having a built-in power generation facility enables the system to be independent in operation.Under the Department of Public Health and Engineering (DPHE), CleanTech Engineering Limited implemented a lot of projects in the coastal areas by the financial support of Islamic Development Bank (IDB).  Salinity is a big issue in the coastal belt.

The community people experience a lot of difficulties to collect drinking water. CleanTech Engineering Limited developed 8 PCs of Pick up mounted Mobile Water TreatmentPlant in Bangladesh capacity of 2000 LPH at their own facilities and supplied them. CleanTech Engineering Limited has introduced all kinds of modern technologies to this Pick Up Mounted Mobile Water Treatment Plant.

The Mobile Water Treatment Plant has been designed and fabricated at own facilities of CleanTech Engineering Limited which bear dignity of Bangladesh.All types of processes are carried out in this modern mobile water treatment plant. Chemical and membrane separation processes are both applied to treat effectively the ground or surface level wastewater.


There is no other alternative option but installing a Surface Water Treatment Plant at Lama Pourashava, Bandarban. Bandarban is one of the Hill-districts situated  in South-Eastern part of  Bangladesh. It has a huge deficiency of safe drinking water in  Lama. It is totally impossible to collect underground water.

There is a small river named “Mata Mahur”  runs through the town but people cannot consume its water as  it is mostly polluted. The World Bank has decided to install a Surface Water Treatment Plant, Capacity-200m3/h through Bangladesh Municipal Development Fund (BMDF) to meet the safe and drinking  water crisis. CleanTech Engineering Limited has set up a Surface Water Treatment Plant with a distribution network at Lama Pourashava.

The project was a capacity of 200 m3/hour. No other but only CleanTech Engineering Limited  have the strength to complete such a job without any interruption. Scope of works are Constriction of Pre-Settling Tank; Bank Protection Work; Ancillary Works and Electro-mechanicals work.

5000LPH RO Plant at Barishal Electric Power Company Limited

RO water plant is a device that removes dissolved solids from potable water. It is widely used in public, private, and commercial buildings to prevent damage caused by dissolved solids such as minerals, sediment, chlorine, and chemicals which can cause rusting of pipelines. The RO water plant extracts the dissolved solids from the water using ion-exchange resins and filters them through activated carbon filtration media while maintaining a settled chemical and dissolved solids suspension inside the RO water plant. The process also solves the problem of dissolved solids and chemical pollution. The purification revives water by ion exchange membrane filters and carbon filtration media in a novel way which is complete for all kinds of ordinary water, such as mains, well, or lake supply. The Raw Water/ Surface Water had too much iron and color, and cleantech team did really very well.

Ongoing Projects:


A series of successful works  with Bangladesh Navy directed to the further supply works of  installation, testing and commissioning of desalination and filtration plant a capacity of 2000 m3/day  to supply drinking water for ships company and officer’s accommodation area at  BNS Issa Khan, Chittagong.
