Vivosun Horticulture 600 Watt Digital Ballast Although this is one of the more affordable models on the market, I like how its features stack up against the pricier options.Ģ. The device’s internals are also coated with resin to prevent moisture and other debris from building up inside.

I can rest easy knowing that this design, plus the built-in 40mm fan, will prevent the unit from overheating. The air-cooled aluminum-finned casing keeps the ballast cool.
It also automatically detects the input voltage between 100 and 265 volts – I am confident that my ballast wouldn’t fail if I accidentally plugged it in the wrong socket.

I like that it has dimmable lighting control to set the power output to what my plants need–50%, 75%, or full power. It has a built-in microprocessor that automatically detects MH and HPS bulbs, negating the need for an additional switch or ballast and keeping your lighting system simple.
The iPower GLBLST1000D 1000 watt digital ballast is one of the more affordable options on the market.

If you require our services, please visit our page Ballasting and Deballasting Inspection Services or you require ballast water analysis, please visit our page Ballast Water Testing for all the specifications. Intestinal Enterococci less than 100 cfu per 100 milliliters.Escherichia coli less than 250 cfu per 100 milliliters.Toxicogenic Vibrio cholerae (O1 and O139) with less than one colony-forming unit (cfu) per 100 milliliters or less than 1 cfu per 1 gram (wet weight) zooplankton samples.The viable organisms fewer than 10 less than 50 micrometers in minimum dimension and greater than or equal to ten micrometers in minimum dimension per milliliter.Īdditionally, a ballast water discharge of indicator microbes, as a health standard, shall not exceed the following specified concentrations:.The viable organisms fewer than 10 greater than or equal to 50 micrometers in minimum dimension per cubic meter.Purpose of D2 standard is to stipulate the level of acceptance of organism that could be found in the discharge ballast water. One more thing to remember is, to contact the port state administrators to confirm Ballast Water Exchange requirements within local waters.ĭ2 standard refers to performance of the ballast water and this is all about chemistry and the laboratory testing where we need to get report for D2- Ballast Water Performance Testing from accredited lab. It is better to go as far as from the land to undertake BWE operation however, minimum 50 nautical miles could also be considered however, under no conditions water depth should not be less than 200 meters. This entire operation has to be done while ship conducts 200 nautical miles operations from the shore/land, and the water should meet the standard of min 200 meters deep. Efficiency is considered as 95% standard when the ship uses to have pumping-through method and where it pumps three times. For BWE, efficiency of at least 95% volumetric exchange of ballast water is required.
So ballasting is taking water into the tanks of the ship to meet the standard load for balancing and same manner when the ship needs loading, deballasting is required or may be this process required in certain circumstances as well when the ship sails.Īs per International Maritime Organization (IMO) there are two standards for ballast water management:ĭ1 Standard – Ballast Water Exchange (BWE)įirst standard is the D1 standard which refers to Ballast Water Exchange (BWE). Ballasting and Deballasting is the term used to stabilize ships in the water, especially when ship is discharged from all heavy load, it becomes light in weight hence unbalanced to float smoothly on the surface.
