Similarly, a low ph Value should be brought up to between 7 and 8. You should not proceed to chlorinate water with a ph value of 9 without correcting the value. You need to take into account factors such as ph and cleanliness of the system, a higher ph will require more chlorine and starts to go up in a logarithmic scale, so best to add something to neutralise the ph of the water if you have something from ph 8 - 9. The idiots rule of thumb (bucket science) is to add half a litre of chlorine to 1000 litres of water to achieve 50ppm. Have a great day.Although your concentration is stated as 13% you should take the value to be nearer 10%. Hope this helps, you might find some online calculators through Google to make this easier so you don’t have to work it out each time. So to prepare 100 litres of a 200ppm solution of Hypo – Sodium Hypochlorite, dilute 160ml of a 12.5% Sodium Hypochlorite solution with water. 125,000ppm x ? = 100,000ml x 200ppm (Sorry, but a little bit of basic algebra is required).Initial Hypo chlorine solution concentration x Initial Hypo chlorine solution volume (?) = Final chlorine solution volume x Final chlorine solution concentration desired.So how much Hypo chlorine solution by volume (ml) do you need to add = ? Initial chlorine solution concentration = 12.5% solution = 125,000/1,000,000 which can also be expressed as 125,000 parts per million (ppm) because 1ppm = 1ml in 1,000,000ml Final chlorine solution concentration desired = 200ppmģ. Final chlorine solution volume = 100 litres = 100,000ml (because 1 litre = 1000ml)Ģ. Here’s the 3 important numbers you need before you start…ġ. To prepare 100 litres of a 200ppm solution from a 12.5% sodium hypochlorite (NaOCI) solution, the following calculations are needed… You should get your own advice but this is how I work it out… Most of the time calculations are made at the 12.5% mark. To answer Crystal’s question, it's not as simple as 200 parts Hypo to 1,000,000 parts water (which would be 1:5000) because you have to allow for the starting concentration of Sodium Hypochlorite of 10-13%. For accurate instructions, you are best consulting with whoever is recommending any specific direction as to how best to calculate the correct dilution to avoid any confusion because these matters are often critical in certain applications. When manufactured the concentration is about 13% but this reduces due to time, exposure etc. Parts per million with a Hypo solution can be a difficult thing to accurately calculate and measure because by nature the Sodium Hypochlorite level in the concentrated form reduces over time from the point of manufacture. General cleaning is the application we supply our Hypo for primarily but in many specialty applications where sanitising is required a parts per million recommendation or requirement can be requested. Our Hypo product label states that for general cleaning you should use at 1 part Hypo to 500 parts water, so for every 500 litres of ready to use solution one litre of Hypo needs to be added. Now let's start talking parts per million and dilution rates.

Can you please advise how much hypochlorite solution this would be? And to how much water? Thank you, Crystal”įor those of you who would just like to know how to quickly calculate cleaning chemical dilution rates and ratios click for the article here. The instructions I have are to mix this to a 200 parts per million solution. “Hi guys, I have received the order of hypochlorite solution, but I have a question with regards to dilution. Here’s a great question asked by one of our clients recently…
