|Update Time:||2011-7-27 11:18:59|
DE-type filter was developed on the basis of D-type filter and E-type filter. This technology adopts the filter material with intensive filter pore as medium. This new high-efficiency filter has a number of advantages as follows:
1. fast filtration speed;
2. high quality effluent;
3. adoption of modular filter element;
4. standardized design;
5. flexible settling of disposal unit on the basis of filter capacity;
6. low energy requirement;
7. high capacity for wastewater treatment;
8. small floor area requirement;
9. reliable in operation;
10. easy maintenance.
1. Small footprint: comparing with D-type filter, the required area for DE-type is approx. 1/3 less than D-type;
2. Low energy consumption: operational electric energy demand is 0.00167 kWh/ton water;
3. Low headloss: water headloss is 0.2-0.3M water column;
4. Convenient for installation, examination and repair: standardized & modular design, manufacture and installation;
5. Specific filter cloth: knitted by specific equipments with utilization of specific macromolecular fibrous and adoption of special process, which was developed and specially produced by Dean Group;
6. The consumption rate of water for suction washing is less than 1%;
7. Easy control: DE-type filter can be implemented by full-automatic control.
DEAN Sci. & Tech. Holdings Co., Ltd., a systematic integrator in the field of water treatment, actively involving in researching and building water circular economy system, provides the general contracting service of engineering design and construction for clients. Meanwhile, DEAN provides the equipments R&D and manufacture for water treatment.
1.Process Design & Pilot Test Service:
DEAN can provide standardized and complete equipments for small-scale and pilot-scale tests by strong R&D capability to solve complicated and changeable on-site problems with clients at the initial stage of projects, which guarantees the feasibility of projects and the optimization of process to provide the prerequisite for the smooth running of the final stage of projects.
In the process of design, DEAN takes into account both the reduction of operating cost and the rationality of one-time investment for clients under the precondition of high effluent quality after treatment, combining the design with the engineering environment thoroughly. As a systematic integrator of R&D design, equipment manufacture, process design, construction management, and operating service, DEAN can effectively obtain feedbacks on time from projects construction, operation and management to provide a reliable base for the proposals optimization.
DEAN works on the engineering construction and equipments manufacture & purchase based on the determined proposals. The construction of projects consists of civil construction, mechanical & electric installation, auto process control and commissioning. The close cooperation between professional project managers and clients guarantees a smooth implementation of the turn-key project.
At the same time, DEAN proceeds the engineering construction based on ISO9000 quality system to guarantee the engineering quality and system capability.
3.The Advancement of Treatment Process
With the development of Chinese economy and society, as well as the improvement of the quality of life, people ask for the higher water quality and the larger water quantity to meet their living standards. However, the traditional method of water treatment can not meet the requirements any more. Meanwhile, the treatment process also needs to be improved as the steady deterioration of water quality.
DEAN owns the advanced core and patent technologies, such as D-Filter, DA863 Filter, High-Efficiency Settler, Flocculation Auto Chemicals Dosing System, DA Electrical Control System, DA Ozone Activated Carbon, DA High-Efficiency Tubular Mixer, DA Activated Sand Filtering Device, DA Highly Integrated Ultrafiltration Device, and the conventional process design for water treatment, etc. These core and patent technologies can guarantee the effluent quality to reach the design standards.
5.Operation and management
The specialists of customer service in DEAN are trained well and possess rich practical experience for operation and management. They are able to provide 24 hours operation and management service in China to guarantee the effluent quality and performance.
The operators from clients' side are involved in the process from design to construction all the time, so that they can start to work immediately once the project starts.
Not only does DEAN own the advanced water treatment technologies, but also it can provide financing for the projects.
The professional subsidiary financing companies owned by DEAN can run independently or cooperate with other subsidiary companies, applying the experience of financing, construction and operation management in BOT, BOO and BT projects.
