The filtrate is composed of water, ions (sodium, potassium, chloride), glucose and small proteins (less than 30,000 daltons -- a dalton is a unit of molecular weight). The rate of filtration is approximately 125 ml/min or 45 gallons (180 liters) each day.he filtrate is composed of water, ions (sodium, potassium, chloride), glucose and small proteins (less than 30,000 daltons -- a dalton is a unit of molecular weight).

In a saucepan bring water, salt and soy sauce to a boil. Add rice and stir. Remove from heat, cover and let stand 5 minutes. Heat oil in a medium skillet or wok over medium heat. Saute onions and green beans for 2 to 3 minutes. Pour in egg and fry for 2 minutes, scrambling egg while it cooks. Stir in the cooked rice, mix well and sprinkle with pepper.
Add the rice and stir-fry for 3 to 4 minutes (Some cooks allow the rice to cook after only an initial mixing with the oil, etc, so that some of the rice develops a crust.) Add at least 1 TBSP each of wine and soy sauce. Stir and mix well. Check for color and taste, add more if desired.
