Urban Sewage Treatment Project

The characteristics of urban sewage water quality depend on thechemical compositionof thesourcewater,the amount of daily water usage, and the nature and quantity of substances discharged into the sewer.Afterbeing used,wateraccumulates avariety of pollutants (such as silt, dust,grease，bacteria, fertilizers, pesticides) and various organic impurities (human waste,washingwastewater,industrial waste,etc.),making its compositionextremelycomplex.Itisdifficulttomeasureallthe components of pollutants. Generally， such indicators as BiochemicalOxygenDemand(BOD),ChemicalOxygenDemand (COD),and Total Organic Carbon (TOC) are used.The characteristics of microbes are mainly determined by detecting the Escherichia coli group.

From theperspective ofcorrosion andprotection,thelarge amount of acidified decaying substances in urban sewage can causeseriouscorrosivedamagetometalandconcrete structures in a short period of time.The anti-corrosion coating ofurbansewagetreatmentprojects generallyincludes: anti-corrosion ofsteel structures and concrete structures in sewage;anti-corrosionof steelstructures andconcrete structures in the atmosphere; anti-corrosion of buried parts.

Anti-corrosion Coating Supporting System of UrbanSewage TreatmentProject

In lightof theanti-corrosionfeaturesof thesewagetreatment project,when designing andselecting theprotective coating scheme,the chosen coatingproduct must meet thefollowing conditions:

·Excellent acid and alkaliresistance;
·Excellentmoistureresistance andwaterresistance;
:Verystrongadhesiveforce;
·Good physical and mechanical properties, such as hardness and flexibility;
.Good heat resistance,ability to withstand temperatures upto 90°\mathsf{C} inwater;
·Excellent resistance to chemicals and solvents;
·Excellentweatherresistanceandanti-ultravioletradiation performance (for aquatic structures).

Seawater Desalination Project

With the development ofthe economy,populationgrowth, and urbanization,coupled with global warming and uneven precipitation,the existing freshwaterresources are clearly insufficient, greatly affecting and restricting the development of society and economy.

Withtheaggravationofwaterresourcescrisis，seawater desalinationhasbeenaccelerated，whichcaneffectively alleviatethewatershortageproblemincoastalcities,avoid excessiveexploitationofgroundwater,andcurbthetrendof groundwater decline and land subsidence.We will make full useofwindpower,hydropower,nuclearpower and other energysourcestoimproveenergyefficiency.

Topromote thescaled applicationof seawater utilization, facilitate the healthy and rapid developmentof the seawater desalination industry,expand production capacity to meet the ever-increasing demand for fresh water, and alleviate the problem of water shortage,HAMGAR also leverages its ownproduct advantages andyears ofexperience toprovide long-lasting protective coating solutionsfor seawater desalination-relatedfacilitiesormaterials.

Coating

The epoxy sealing paint is not included in the calculation of dry film thickness.It only serves a sealing function.

Aquaculture

Aquacultureisa variety of methodsthat promotesthereproduction and growth of economic animals and plants in specific bodies of waters and plants in specific bodies of water through artificial control and management.According to the ecologicalhabitsofthebreedingobjects,itcreatessuitable environmental conditionsto promotethe massreproduction andrapidgrowthofthetargetorganisms.

The main technical challenges faced by artificial breeding include:

·It is necessary to strictly control water temperature, salinity,pHandotherparameterstokeepthewaterfresh,as wellasregularlychangethewaterandcleanthepoolwall andbottom.

·Specialattentionneedstobepaidtothedisinfectionand cleaning of thebreeding environment,regular pest control, andfreshwatermedicinalbaths.

Therefore,the paint used in the aquaculture tank not only plays a protective role in the aquaculture tank, but also can not pollute the waterquality,nor can it negatively affect the growth andquality of aquacultureproducts.
