How do you remove bicarbonate from irrigation water?

Lowering the pH to 6.5 neutralizes about half the bicarbonate in the water. Most common acids to inject are sulfuric acid, phosphoric acid. Injection of acidified water instead of a dry material to a wide area will reduce bicarbonate accumulation in the irrigated area where irrigation may cause to accumulation.

What is the pH of irrigation water?

between 5.5 and 7.5
The generally accepted pH for irrigation water is between 5.5 and 7.5, but some problems can occur within this range. Alkaline water may contain high concentrations of bicarbonate (generally in water of pH 8 and above) and carbonates (generally pH 9 and above).

What kind of acid do you use for irrigation water?

To optimize fertility and combat the other adverse effects of high pH/ alkalinity, it is possible to treat irrigation water by injecting acid. Although phosphoric and nitric acids have some application, sulfuric acid is the most commonly used.

How to lower the pH of irrigation water?

Injection by time and injection by ratio. 150 ml acid per 1 cubic meter (m3) of irrigation water are required to lower the pH to the desired level (150 ml/m3 = 1.92 oz/100 gal) The flow rate of the acid injector is 50 l/hr (=13.2 gal/hr).

What’s the best way to treat irrigation water?

Adjusting the pH of Irrigation Water. To optimize fertility and combat the other adverse effects of high pH/ alkalinity, it is possible to treat irrigation water by injecting acid. Although phosphoric and nitric acids have some application, sulfuric acid is the most commonly used.

Is it safe to inject acid into irrigation water?

Remember acid is caustic to metal parts, so consult your fertilizer injector manufacturer to make sure your injector is compatible for injecting acid. Acid is being directly injected from these two acid tanks into the irrigation water. This is safer than having to mix it with water. Source: Premier Tech.
