GuangdongLESSO Agricultural Facilities Technology Co., Ltd.

Guangdong Lesso AgriculturalFacilities Technology Co.,Ltd.,，a wholly-owned subsidiary of China LESSO Group Holdings Limited, mainly specializes in the development and promotion of standardized agricultural facilities. The products it has developedtodateincludeintegratedshore-basedaquaculturetailwatertreatment systems, industrial recirculating aquaculture systems, intelligent integrated machines of water and fertilizer,high-pressure sprayers, as well as energy-saving and noise-reducing aerators.Thecompany aimstoachievealowercarbonandgreen power ecosystem agriculture and explore the models of multiple and high production inasinglepieceoflandbycombininghybridfishery-solarandagricultural-solar systems.

GuangdongLessoAgricultural Facilities Technology Co.,Ltd.holds dozens of patentsforaquacultureandtailwater treatmentsystems，amongwhichthe integratedshore-based aquaculture tail watertreatment system，developedby collaborativeresearchanddevelopment,wasincluded in theRecommended ModelsofComprehensiveTreatmentTechnologiesforAquacultureTailWaterin GuangdongProvince.Thecumulativeareaoffishpondaquaculturetailwater treatmentprojects servedby the company in thePearl RiverDelta area has now exceeded100,000mu(approximately 66.67\ k m^{2})

Product Strengths

Efficient operation

Thedailywater treatmentcapacityof the system canreach 1,584\;\;m^{3} ，and therecyclingrate of aquaculture water exceeds 99% .Afterbeing treated by the system,the aquaculture tailwater is concentrated to 1 to 2~\mathsf{m}^{3} per day. In this way，the efficient treatment and discharge of aquaculturetailwaterwillbeachieved.

Enhancedefficiency and increasedproduction

Therecirculating aquaculture designcan effectively improve thewaterqualityof theaquaculturepond byseparating theresidualfeeds andfeceswithin the water，which results in a reduction of approximatelyone-third inthe annual investment ofanimalhealthproductsand anincrease in productionbyover 20%

Small occupied area

Theequipmentoccupies anareaofonlyabout 10 \ m^{2} andcanbesetonthepondfoundation, without the needs for casting theconcrete foundation or occupying the original ponds for tailwater treatment.

Short construction cycle, and quick effect.Low influence on aquaculture

The system only requires one week from production to installation, and the installation process has no impact on the aquaculture operations, regardless of the aquaculture stages. The system can be put into use immediately after installation, andtakes effectquickly，witha significantly shorter implementation and application cycle compared to other processing products.

Low costperunit area

The adoption of the equipment can solve the critical issues of fishpond tailwater treatmentaccording to standard requirements. Its investment cost requires only CNY 2,0o0 to 2,500 per mu (a traditional Chinese unit of area， approximately equal to 666.67~\:\mathsf{m}^{2}) ，which is significantly lowerthan that of other tailwater treatment technologies.

Technical Process

Process Flow Chart of Integrated Shore-based Equipment -- Pond Recirculating Aquaculture and Tail Water Treatment System

The equipment can solve the problem of aquaculture water pollution at its sources, withadailywater treatmentcapacityof upto 1,584\;\;m^{3} Therecyclingrateof aquaculturewaterinthesystemexceeds 99% Thefishpondaquaculturewatercan be recycled once every 6 to 10 days, up to 30 times during each production cycle, which improves the water quality in the fishponds, and reduces the risk of aquaculture diseases.

The equipment canperform efficient separation ofresidual feeds and fecesproduced in the breeding process, which can reduce pollution to the aquaculture water.At the same time,it can provide aeration and oxygenation for the aquaculture water. Featured by a combination of jet aeration and air cutting secondary aeration,the equipment can aerate and enrich oxygen in 1,584\;\;\mathsf{m}^{3} of fishpond water per day. The dissolved oxygen in the aquaculture water treated and returned from the equipmentcanreach8to 10~\mathsf{m g/L} a 1.5~{\mathsf{k W}} aeratorcanbereducedatthe aerationandoxygenationwateroutlet.
