Dasmartis specialized in offering exclusive sewage treatment and wastewater reuse solutions to various industries, including but not limited to the following areas:
-Coal chemical wastewater
-Pharmaceutical chemicals wastewater
-Mixed industrial park sewage
-Dye intermediate wastewater
For the industrial wastewater containing high salt, high COD, high toxicity, difficult to degrade, Dasmart is able to provide specialized and targeted solutions our clients, revamping the production capability and optimizing technical process without occupying extra land. Dasmart helps our clients reduce operating costs, lower energy consumption, improve the impact resistance, enhance the processing capacity ofthe effluent COD, and boost the sewage plant pretreatment efficiency while maintaining the water quality to the discharge standards.
Dasmart offers optimal solutions and supplies comprehensive sets of production and operation services for municipal wastewater reuse, circulating water use in compliance with national and local standards and in accordance to regional development and urban planning.
Dasmart provides solution for the raised turbidity of tap water caused by high humic content or high silt content in water treatment plants.
Dasmart is able to provide a comprehensive set of solutions for seawater desalinazation and zero emission of RO concentrated water.
Dasmart is able to provide technical guidance and operational management services for operating sewage treatment plant.
With increasing environmental protection, many countries have put forward stricter requirements on the composition of engine fuels, especially on its sulfur content. Currently, more than 90% of the sulfur-containing compounds in refined oils within China come from catalytic cracking gasoline, and the sulfur content of FCC gasoline is key in reducing the sulfur content of gasoline.
Dasmart has developed a new desulfuration solution characterized by high selectivity, high oil yield, desulfurization without octane reduction, while requiring low investment and low processing cost. For example, FCC gasoline desulfurization process package design and technical services can reduce sulfur content to below 10 mg / L, the desulfurization cost less than 70 RMB / ton without loss of octane value.
With the problem of inferior quality of the crude oil becoming more prominent, there has been increasingly stringent environmental regulations. Heavy fuel oil demand continues to decline, and the demand for light and clean fuel steadily rises.
The light trend of heavy oil has become a major strategic issue to ensure national energy security. Dasmart can provide wax removal device of the basic nitrogen process package design and solution. With the transfer of basic nitrogen compound removal from coker gas oil (CGO) and coke powder, the CGO can be used as raw materials for light cracking unit and catalytic cracking unit (CCU) directly.
